title: Multiple Tabs
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
In development mode Next.js creates 2 persistent connections to the server to receive hot updates and to keep pages active. Each browser has their own limit for the number of concurrent connections to a specific server a site is allowed to have so if you open the same Next.js site in multiple tabs of the same browser you could exceed your browser's limit.

|
## Possible Ways to Fix It
|
|
|
|
- Don't have too many tabs open to the same Next.js site open in development in the same browser at the same time.
|
|
- If using Firefox you can increase this limit by navigating to `about:config` and setting `network.http.max-persistent-connections-per-server` to a higher number
